Chapter 1
1. Getting Started
The purpose of this chapter is to give a short description on how to install the X-gateway and get it up
and running, transferring I/O data between Network 1 (the controlling network, where the X-gateway
acts as a server) and Network 2 (the controlled network, where the X-gateway acts as a client).
Perform the following steps when installing the module:
1. Mount the module. See “Mounting the X-gateway” on page 18 for details.
2. Connect the X-gateway to the Network 2. See “External View” on page 17.
3. Connect the power cable and apply power.
4. Access the configuration web pages.
• Connect a PC to the Network 2 (see “External View” on page 17) and open a web browser.
Enter the IP address of the X-gateway and access the configuration web pages. If the IP ad-
dress of the X-gateway is unknown, use the Anybus IPconfig tool to find it. See “Anybus IP-
config Tool” on page 45.
• Configure the Network 2 client interface. See “Modbus Client (Network 2)” on page 33.
• Set up all Modbus servers and transactions using the configuration web pages. See “Modbus
Servers” on page 34 and “Network Configuration” on page 28.
• Configure the Network 1 server interface. See “Modbus-TCP (Network 1 Server Interface)”
on page 37.
5. Configure the Modbus-TCP client (PLC) on Network 1. See “Configuring the Modbus-TCP
Network” on page 10.
6. Connect the X-gateway to the Modbus-TCP (slave) network. See “External View” on page 17.

2. Anybus X-gateway Modbus-TCP
2.1 Introduction
The Anybus X-gateway Modbus-TCP is a series of network gateways, used to provide a seamless con-
nection between a Modbus-TCP network and a controlling network. This particular product connects a
Modbus-TCP network to another Modbus-TCP network. In order to avoid confusion, the controlling
network will be called Network 1, and the network that is controlled will be called Network 2.
The X-gateway enables the master of Network 1 to control Network 2. These X-gateways makes it pos-
sible to integrate Modbus-TCP devices into almost any other PLC system and their supported networks.
The X-gateway is based on patented Anybus
technology, a proven industrial communica-
tion solution used all over the world by lead-
ing manufacturers of industrial automation
products. Each module offers Modbus-TCP
master connectivity to one of these industrial
networks: EtherNet/IP, Modbus-TCP,
PROFINET, Modbus RTU, EtherCAT, CC-
Link, ControlNet, CANopen, DeviceNet
and PROFIBUS DP-V1.
No proprietary configuration software is
needed. All necessary configuration is made
via the built-in web interface.
The Modbus-TCP server interface (the Net-
work 1 interface) is configured with a stand-
ard engineering tool of the PLC. No programming is required.
The X-gateway transmits I/O data transparently between the two networks.

2.2 Features
Anybus X-gateways for Modbus-TCP act as intelligent links between two industrial networks. On Net-
work 2, they function as clients (masters) while they function as servers (slaves) on Network 1. The im-
plementation is based on the Anybus NP30 ASIC technology.
2.3 Configuring the Modbus-TCP Network
The Anybus X-gateway is a Modbus-TCP server (slave) on Network 1. The general settings for the serv-
er interface are configured using the configuration web pages (see “Modbus-TCP (Network 1 Server In-
terface)” on page 37). All data transfers must be configured using the Modbus-TCP configuration tool.
Please note that the size of the I/O data that can be read from and written to the module is defined when
configuring the X-gateway using the configuration web pages.
There are a number of different configuration tools for Modbus-TCP available on the market. The
choice of tool depends on the application and the Modbus-TCP client of Network 1.
An application note, describing how to configure an Anybus Modbus-TCP server interface with RS
Logix and RS Networx, is available on the support pages for the Anybus X-gateway Modbus-TCP -
Modbus-TCP module at ‘www.anybus.com’.

2.4 Functional Overview
Internally, the X-gateway consists of an intelligent gateway platform: an Anybus Modbus-TCP client in-
terface for Network 2 and an Anybus Modbus-TCP server interface for Network 1. The two interfaces
are interconnected through the intelligent gateway platform, which basically forwards data from one net-
work to the other and vice versa as shown below. This design allows almost any other industrial network
to be connected to a Modbus-TCP master on a separate Modbus-TCP network.

2.5 Data Exchange
Each of the two network interfaces exchanges data on its network through two buffers. The X-gateway
forwards the data between these buffers as shown below. Note that this process is separated from the
network data exchange. While the X-gateway ensures data consistency (where applicable), it does not
feature any built-in mechanisms for synchronization between the two Modbus-TCP networks.
Each buffer holds a maximum of 256 bytes of data. The first two I/O mapped bytes in either direction
can be dedicated for control/status information, and another eight bytes of data coming from Network
2 can feature a live list.
Through the dedicated control word, the client on Network 1 starts/stops the exchange of data on Net-
work 2, and also resets the X-gateway if needed. The client on Network 1 can see the status of Network
2 in the corresponding status word. The live list feature gives the client on Network 1 the opportunity
to continuously see and monitor the status of each individual transaction on Network 2.
Two additional lists, transaction status and exception codes, retrievable from the module by the master
on Network 1, provides detailed error information about all transactions.
The amount of data that shall be exchanged, and the use of the control/status word and the live list, is
specified separately for each application. This means that even though up to 256 bytes of data can be
potentially forwarded to an interface, the amount of data that will actually be exchanged on that network
is determined by the settings in the configuration web pages.
The available control/status functionality is described below, as well as the live list and the transaction
status and exception codes lists. Also note that the terminology and definitions used for different types
of data vary greatly between different networking systems.

2.6 I/O Mapped Data
I/O mapped data is cyclic data, exchanged between the networks and/or devices at a high transfer rate.
It is associated with data that is continuously sent on the network.
2.7 Parameter Data
Parameter data is usually exchanged acyclically, to set or change parameters in devices before or during
normal process. Typical parameter data that can be retrieved from the module by the master of
Network 1 includes the transaction status list and the exception code list.
2.8 Control/Status Word
The Control/Status word is always retrievable using acyclical access. Optionally, the Control/Status
word can also be I/O mapped. The I/O mapping can be enabled/disabled when configuring
Network 1 via the configuration web pages. See “Modbus-TCP (Network 1 Server Interface)” on page
37.
For information about how to access the Control/Status word, either I/O mapped or using parameter
access, see “Mapping Overview” on page 40.
The Control word is a 16-bit word (uint16) used by Network 1 to control the Anybus X-gateway and
subsequently also Network 2.
The Status word is a 16-bit word used by the X-gateway to report its current actual status to Network 1.
Bit Value Description
0 (Least signifi-
cant bit)
0 Puts the X-gateway in idle state
1 Puts the X-gateway in run state
1 - A reboot of the X-gateway is triggered by a rising edge, i.e. a transition from 0 to 1
2-7 Set to zero Unused
8-15 Set to zero Unused
Bit Value Description
0 (Least signifi-
cant bit)
0 The X-gateway is in idle state
1 The X-gateway is in run state
1 - This bit is reflecting the state of bit 1 in the control word

2.9 Live List
The live list features the possibility for Network 1 to continuously receive an I/O mapped list containing
the status of every transaction on Network 2.
It is accessible using parameter access, and also I/O mapped by default. The I/O mapped live list can
be enabled/disabled when configuring the Network 1 settings. See “Modbus-TCP (Network 1 Server
Interface)” on page 37. If the I/O mapped live list is enabled, it will occupy either byte 0-7 (control/
status word not enabled) or byte 2-9 (control/status word enabled and mapped to the first two bytes) in
the input data area.
All transactions and their places in the live list are also visible in the Transaction Monitor on the config-
uration web pages.
The live list consists of a bit array with 64 elements, where each bit corresponds to a transaction on Net-
work 2 as in the table below.
• Bit set to 1
Transaction successful.
• Bit set to 0
Transaction not successful.
Note: the reason for the unsuccessful transaction can be found on the corresponding index in
the transaction status list.
The order of the transactions in the live list conforms to the order in which they are stored in the Mod-
bus Server list.
Example
Consider the following configuration:
• Server 1 : a total of 2 transactions
• Server 2 : a total of 3 transactions
• Server 3 : a total of 1 transaction
This scenario will produce a live list as follows (assuming that the transactions are successful):
Note: Use the Modbus function “Read Discrete Inputs” to access the live list as a bit array.

3.2 Mounting the X-gateway
The Anybus X-gateway can be physically installed either by mounting it onto a DIN-rail or, if installed
in areas exposed to vibration, by mounting it on a wall for more stability.
3.2.1 DIN-rail Mounting
Make sure the DIN-rail fastening mechanism on the back of
the module is in a fixed and closed position, i. e. pushed all the
way up.
To mount the module, first hook it on to the DIN-rail (1),
then push it against the DIN-rail to make it snap on (2).
To unmount the module, a screwdriver is needed. Use the
screwdriver to push the DIN-rail fastening mechanism on the
back of the module down until it locks in a fixed and open po-
sition (1). Then unhook the module from the DIN-rail (2).
Note: Do not leave the module with the DIN-rail fastening
mechanism in a fixed and open position. This may eventually
wear the fastening mechanism out so it cannot be used effi-
ciently. Be sure to push the DIN-rail fastening mechanism
back into the fixed and closed position after unmounting the
module.

3.2.2 Wall Mounting
Use the wall mounting option if there is a need to place the X-gateway in an environment exposed to
vibration. This way of mounting the module offers more stability than the traditional DIN-rail mount-
ing.
Note: The X-gateway should be fastened in a standing-up position, to ensure a constant air flow.
Note: When mounting the X-gateway to a wall using the wall mount option, do not forget to connect
the module to protective earth (PE) via the power connector. See “Power Connector” on page 22.
Mounting Instructions
Step Description Visual description
Open up the package containing the wall
mounting accessories.
- One metal frame
- Industrial velcro
- Four plastic vibration dampers
Remove the plastic protection from one
side of the velcro.
Attach the velcro to the metal frame.
Attach the four plastic vibration dampers
to the X-gateway, on the side that will face
the wall.
Remove the plastic protection from the
other side of the velcro.
Turn the X-gateway around, so that the
plastic vibration dampers face down-
wards.
Fasten the metal frame to the X-gateway
by pressing the frame firmly against the X-
gateway, making the two velcro parts
attach to each other.
Attach the metal frame and the X-gateway
to a wall using screws and washers (not
enclosed).
